Description

Technical Field

[0001] The utility model relates to the technical field of tunnel drilling, in particular to a tunnel drilling machine with a lifting function. Background Art

[0002] Tunnel drilling rigs are indispensable equipment for underground construction such as tunnels and culverts. With the development of automatic control technology, most of the current tunnels are remotely controlled or remotely controlled. During the tunnel construction process, due to the limited tunnel space, the distance between the bottom of the traditional tunnel drilling rig and the ground space is limited. When transporting rock slag, the entire machine needs to be withdrawn to make way for the rock slag to be removed, which greatly increases the construction time and reduces the construction efficiency. Frequent withdrawal operations also increase the construction risks and pose a potential threat to construction safety. In addition, the existing tunnel drilling rigs only change the construction position of the drilling assembly through the rotating assembly, and their coverage is small, flexibility is poor, and there are certain shortcomings.

The base 5 is installed on the top of the frame 8, the crawler walking assembly 7 is installed on both sides of the frame 8, the power system 4 is installed on the top of the base 5, and the drill barrel assembly and the rotary assembly can adopt the same method as that of the invention disclosed in Publication No. C N116291224A A double rotary annular seam coring drill has the same structure as the prior art, and the crawler vehicle is also the prior art, which will not be described in detail in this application. The lifting mechanism 3 is installed at one end of the base 5, and the bottom end of the support column 601 is fixedly connected to the frame 8 where the crawler walking assembly 7 is installed. The lifting mechanism 3 includes a sliding shoe seat 305, a rotary assembly connecting plate 304 and a lifting cylinder 303. The sliding shoe seat 305 is fixedly installed at one end of the crawler vehicle, and two cylinder mounting grooves are provided on the sliding shoe seat 305.

A cylinder seat is fixedly connected to the top of one side of the slewing assembly connecting plate 304, and the top of the lifting cylinder 303 is connected to the cylinder seat of the slewing assembly connecting plate 304. As the lifting cylinder 303 works, the slewing assembly 2 and the drill frame assembly 1 at the front end are driven to move up and down, so that the position of the drill hole can be changed more flexibly, thereby improving the flexibility of the device. Two lifting legs 6 are respectively installed on both sides of the crawler vehicle. The lifting legs 6 are composed of a support column 601, a support leg 602 and a support cylinder 603.
